Mission critical real-time systems often function in environments that cannot be modelled with static approaches. Because of their (externally-driven) wide dynamic range of system operation, the number of data elements to be processed in an arbitrary period is unknown at the time of system engineering (other than an extremely pessimistic worst case sense). While it may be possible to determine a theoretical upper bound on the number of data items, the construction and maintenance of system components to handle worst-case conditions can be prohibitively costly. To accommodate such dynamic mission critical real-time systems, it is useful to design computing systems that allow reconfiguration and reallocation of resources by sharing a pool of distributed computational resources. Unfortunately, the problem of continuously providing critical system functions in such dynamic real-time environments is exacerbated when one considers attack vulnerability. The Internet has made mission critical real-time computer systems subject to an ever-changing array of attacks for which current defence mechanisms are insufficient. In order to combat intruders in this new environment, new techniques must be developed that enable decision makers to detect unusual behaviour in their systems, correlate anomalies into higher-level attacker goals, plan appropriate response actions, and execute their plans. This special book presents current work in this general area of real-time system security.

Presenting encryption algorithms with diverse characteristics, Image Encryption: A Communication Perspective examines image encryption algorithms for the purpose of secure wireless communication. It considers two directions for image encryption: permutation-based approaches and substitution-based approaches. Covering the spectrum of image encryption principles and techniques, the book compares image encryption with permutation- and diffusion-based approaches. It explores number theory-based encryption algorithms such as the Data Encryption Standard, the Advanced Encryption Standard, and the RC6 algorithms. It not only details the strength of various encryption algorithms, but also describes their ability to work within the limitations of wireless communication systems. Since some ciphers were not designed for image encryption, the book explains how to modify these ciphers to work for image encryption. It also provides instruction on how to search for other approaches suitable for this task. To make this work comprehensive, the authors explore communication concepts concentrating on the orthogonal frequency division multiplexing (OFDM) system and present a simplified model for the OFDM communication system with its different implementations. Complete with simulation experiments and MATLAB (R) codes for most of the simulation experiments, this book will help you gain the understanding required to select the encryption method that best fulfills your application requirements.

The Handbook of Financial Cryptography and Security elucidates the theory and techniques of cryptography and illustrates how to establish and maintain security under the framework of financial cryptography. It applies various cryptographic techniques to auctions, electronic voting, micropayment systems, digital rights, financial portfolios, routing networks, and more. In the first part, the book examines blind signatures and other important cryptographic techniques with respect to digital cash/e-cash. It also looks at the role of cryptography in auctions and voting, describes properties that can be required of systems implementing value exchange, and presents methods by which selected receivers can decrypt signals sent out to everyone. The second section begins with a discussion on lowering transaction costs of settling payments so that commerce can occur at the sub-penny level. The book then addresses the challenge of a system solution for the protection of intellectual property, before presenting an application of cryptography to financial exchanges and markets. Exploring financial cryptography in the real world, the third part discusses the often-complex issues of phishing, privacy and anonymity, and protecting the identity of objects and users. With a focus on human factors, the final section considers whether systems will elicit or encourage the desired behavior of the participants of the system. It also explains how the law and regulations impact financial cryptography. In the real world, smart and adaptive adversaries employ all types of means to circumvent inconvenient security restraints. This useful handbook provides answers to general questions about the field of financial cryptography as well as solutions to specific real-world security problems.

Though often invisible, cryptography plays a critical role in our everyday lives. Broadly defined as a set of tools for establishing security in cyberspace, cryptography enables us to protect our information and share it securely. It underpins the security of mobile phone calls, card payments, web connections, internet messaging, Bitcoin transactions-in short, everything we do online. Clearly and concisely, Keith Martin reveals the many crucial ways we all rely on cryptographic technology and demystifies its controversial applications and the nuances behind alarming headlines about data breaches or Edward Snowden. Essential reading for anyone with a password, Cryptography offers a profound perspective on personal security, online and off.

A case-based approach to cryptanalysis that explains how and why attacks can happen

Applied Cryptanalysis focuses on practical attacks on real-world ciphers. Using detailed case studies, the authors demonstrate how modern cryptographic systems are broken, and they do so with a minimum of complex mathematics and technical jargon. All major classes of attacks are covered, providing IT professionals with the knowledge necessary for effective security implementation within their organizations. Each chapter concludes with a series of problems that enables the reader to practice and fine-tune their own cryptanalysis skills. Applied Cryptanalysis can serve as a textbook for a cryptanalysis course or for independent study.

The text is organized around four major themes:

Classic Crypto offers an overview of a few classical cryptosystems, introducing and illustrating the basic principles, concepts, and vocabulary. The authors then cover World War II cipher machines, specifically the German Enigma, Japanese Purple, and American Sigaba.

Symmetric Ciphers analyzes shift registers and correlation attacks, as well as attacks on three specific stream ciphers: ORYX, RC4 (as used in WEP), and PKZIP. In addition, block ciphers are studied: Hellman's Time-Memory Trade-Off attack is discussed and three specific block ciphers are analyzed in detail (CMEA, Akelarre, and FEAL).

Hash Functions presents hash function design, birthday attacks, and the "Nostradamus" attack. Then the MD4 attack is examined, which serves as a precursor for the authors' highly detailed analysis of the recent attack on MD5.

Public Key Crypto includes an overview of several public key cryptosystems including theknapsack, Diffie-Hellman, Arithmetica, RSA, Rabin cipher, NTRU, and ElGamal. Factoring and discrete log attacks are analyzed, and the recent timing attacks on RSA are discussed in detail.

Clear and concise, this practical case-based approach to cryptanalysis is a valuable and timely resource.

A How-to Guide for Implementing Algorithms and ProtocolsAddressing real-world implementation issues, Understanding and Applying Cryptography and Data Security emphasizes cryptographic algorithm and protocol implementation in hardware, software, and embedded systems. Derived from the author's teaching notes and research publications, the text is designed for electrical engineering and computer science courses. Provides the Foundation for Constructing Cryptographic Protocols The first several chapters present various types of symmetric-key cryptographic algorithms. These chapters examine basic substitution ciphers, cryptanalysis, the Data Encryption Standard (DES), and the Advanced Encryption Standard (AES). Subsequent chapters on public-key cryptographic algorithms cover the underlying mathematics behind the computation of inverses, the use of fast exponentiation techniques, tradeoffs between public- and symmetric-key algorithms, and the minimum key lengths necessary to maintain acceptable levels of security. The final chapters present the components needed for the creation of cryptographic protocols and investigate different security services and their impact on the construction of cryptographic protocols. Offers Implementation Comparisons By examining tradeoffs between code size, hardware logic resource requirements, memory usage, speed and throughput, power consumption, and more, this textbook provides students with a feel for what they may encounter in actual job situations. A solutions manual is available to qualified instructors with course adoptions.

Among the features that make Noiseless Steganography: The Key to Covert Communications a first of its kind: The first to comprehensively cover Linguistic Steganography The first to comprehensively cover Graph Steganography The first to comprehensively cover Game Steganography Although the goal of steganography is to prevent adversaries from suspecting the existence of covert communications, most books on the subject present outdated steganography approaches that are detectable by human and/or machine examinations. These approaches often fail because they camouflage data as a detectable noise by altering digital images, audio files, text, etc. However, such alteration raises suspicion and makes the message discernible by detecting its noise. Addressing such shortcomings, Noiseless Steganography: The Key to Covert Communications introduces a novel Noiseless Steganography Paradigm (Nostega). Rather than hiding data in noise or producing noise, Nostega camouflages messages as well as their transmission in the form of unquestionable data in the generated steganographic cover. The book explains how to use Nostega to determine suitable domains capable of generating unsuspicious steganographic cover in which messages are embedded in the form of innocent data that is compatible with the chosen domain. It presents a number of Nostega-based methodologies, including but not limited to: A novel cover type that enables data to be hidden in plotted graphs A novel methodology that pursues popular games such as chess, checkers, crosswords, and dominoes to conceal messages Comprehensive coverage of linguistic steganography Several novel linguistic steganography methodologies based on Natural Language Processing and Computational Linguistic techniques such as: Education-Centric-Based, Summarization-Based, Natural Language Generation Based, Random-Series-Based, Email Headers Based, Automatic Joke Generation Based, List-Based, and Automatic Notes Generation Based The first book to provide comprehensive coverage of Linguistic Steganography, Graph Steganography, and Game Steganography, it discusses the implementation and steganalysis validation of ten Nostega-based methodologies. It describes how to establish covert channels by employing the selected domain to serve as justification for the interaction and delivery of the cover among the communicating parties. Instead of using contemporary steganography approaches to camouflage your data as noise that is assumed to look innocent, the text provides you with the tools to prevent your adversaries from suspecting the existence of covert communications altogether.

While it has become increasingly apparent that individuals and organizations need a security metrics program, it has been exceedingly difficult to define exactly what that means in a given situation. There are hundreds of metrics to choose from and an organization's mission, industry, and size will affect the nature and scope of the task as well as the metrics and combinations of metrics appropriate to accomplish it. Finding the correct formula for a specific scenario calls for a clear concise guide with which to navigate this sea of information. Complete Guide to Security and Privacy Metrics: Measuring Regulatory Compliance, Operational Resilience, and ROI defines more than 900 ready to use metrics that measure compliance, resiliency, and return on investment. The author explains what needs to be measured, why and how to measure it, and how to tie security and privacy metrics to business goals and objectives. The book addresses measuring compliance with current legislation, regulations, and standards in the US, EC, and Canada including Sarbanes-Oxley, HIPAA, and the Data Protection Act-UK. The metrics covered are scaled by information sensitivity, asset criticality, and risk, and aligned to correspond with different lateral and hierarchical functions within an organization. They are flexible in terms of measurement boundaries and can be implemented individually or in combination to assess a single security control, system, network, region, or the entire enterprise at any point in the security engineering lifecycle. The text includes numerous examples and sample reports to illustrate these concepts and stresses a complete assessment by evaluating the interaction and interdependence between physical, personnel, IT, and operational security controls. Bringing a wealth of complex information into comprehensible focus, this book is ideal for corporate officers, security managers, internal and independent auditors, and system developers and integrators.

RC4 Stream Cipher and Its Variants is the first book to fully cover the popular software stream cipher RC4. With extensive expertise in stream cipher cryptanalysis and RC4 research, the authors focus on the analysis and design issues of RC4.

The world's most infamous hacker offers an insider's view of the low-tech threats to high-tech security
Kevin Mitnick's exploits as a cyber-desperado and fugitive form one of the most exhaustive FBI manhunts in history and have spawned dozens of articles, books, films, and documentaries. Since his release from federal prison, in 1998, Mitnick has turned his life around and established himself as one of the most sought-after computer security experts worldwide. Now, in The Art of Deception, the world's most notorious hacker gives new meaning to the old adage, "It takes a thief to catch a thief."
Focusing on the human factors involved with information security, Mitnick explains why all the firewalls and encryption protocols in the world will never be enough to stop a savvy grifter intent on rifling a corporate database or an irate employee determined to crash a system. With the help of many fascinating true stories of successful attacks on business and government, he illustrates just how susceptible even the most locked-down information systems are to a slick con artist impersonating an IRS agent. Narrating from the points of view of both the attacker and the victims, he explains why each attack was so successful and how it could have been prevented in an engaging and highly readable style reminiscent of a true-crime novel. And, perhaps most importantly, Mitnick offers advice for preventing these types of social engineering hacks through security protocols, training programs, and manuals that address the human element of security.

Group theoretic problems have propelled scientific achievements across a wide range of fields, including mathematics, physics, chemistry, and the life sciences. Many cryptographic constructions exploit the computational hardness of group theoretical problems, and the area is viewed as a potential source of quantum-resilient cryptographic primitives for the future. Group Theoretic Cryptography supplies an ideal introduction to cryptography for those who are interested in group theory and want to learn about the possible interplays between the two fields. Assuming an undergraduate-level understanding of linear algebra and discrete mathematics, it details the specifics of using non-Abelian groups in the field of cryptography. Moreover, the book evidences how group theoretic techniques help us gain new insight into well known, seemingly unrelated, cryptographic constructions, such as DES. The book starts with brief overviews of the fundamentals of group theory, complexity theory, and cryptography. Part two is devoted to public-key encryption, including provable security guarantees, public-key encryption in the standard model, and public-key encryption using infinite groups. The third part of the book covers secret-key encryption. It examines block ciphers, like the Advanced Encryption Standard, and cryptographic hash functions and message authentication codes. The last part delves into a number of cryptographic applications which are nowadays as relevant as encryption-identification protocols, key establishment, and signature schemes are covered. The book supplies formal security analyses and highlights potential vulnerabilities for cryptographic constructions involving group theory. Summaries and references for further reading, as well as exercises, are included at the end of each chapter. Selected solutions for exercises are provided in the back of the book.
